Sealing Performance
Under High Pressure
APM Hexseal invented and patented pre-assembled
self-sealing fasteners designed to provide both fastening
and sealing integrity in a single unit. Our design features
a resilient O-ring held captive in a precision engineered
groove under the fastener head. This combination of
precise groove geometry and O-ring characteristics
results in an absolute seal regardless of surface finish,
while still providing full metal-to-metal contact.
Vibration-resistant and re-usable, SEELSKREWS®,
SEELBOLTS®, and SEELRIVETS® can withstand
internal/external pressures up to 20,000 psig/vacuum at
temperatures from -160°F to +500°F (-106°C to +260°C).*
Made in the U.S.A., APM self-sealing & self-locking
fasteners are available in standard and metric sizes in
a wide choice of head and fastening types including
self-tapping, and tamper-resistant. Typically, they are
furnished in stainless steel/with different finishes or colors
as may be required. All have pre mounted silicone rubber
O-rings. Other elastomeric materials are also available to
match and handle exposure to various chemicals and
solvents (see materials table 1 on page 5). Consult
factory for further information and pricing.
They represent a superior sealing alternative to
sealing compounds, tape, chemical coatings, and
deformable washers that attempt to seal the threadform.

ADJUSTABLE LOCKING PELLETS FOR
SEELSKREW®, SEELBOLT® & SEELNUT®
SELF-SEALING FASTENERS
FULLY ADJUSTABLE & REUSABLE PER
IFI 124, IFI 524 & MIL-DTL-18240F,
NASM25027
When assembled with a mating part the resilient engineered polymer
pellet (normally Nylon) is compressed, and a locking action is established.
APM Pellet Locking action takes place inside the threads due to its
vibration dampening characteristics, as opposed to at the bearing surface.
The resilience of the pellet holds the fastener in place without adhesives
or thread distortion. The pellet’s resiliency also contributes to its superior
degree of adjustability and repeated reusability. See pages 4, 5 & 6 of
this catalog for complete list of fastener sizes to apply.
Self-Sealing screws, bolts and nuts that have pellets installed can
operate and deliver outstanding performance in both high and low
temperature extremes without degradation. Under most operating conditions, these pellets are unaffected by vibration of
reversal of stress. Installed in a drilled hole (just below the depth of the thread), APM pellets are typically positioned one
to three threads back from the end of the fastener to assure ease of starting. Hole positioning can be modified to meet
specific applications – contact Technical Sales for assistance.
FEATURES
HOW TO ORDER
• Resistant to vibration and reversal of stress, APM
pellets lock whether fasteners are seated or
unseated.
Specify the head type, thread size, length, followed by
the Ordering Code.
Example: To order a slotted pan head SEELSKREW,
with a 8-32 thread, 1 inch long, with
standard silicone o-ring, black oxide finish
and Nylon pellet order...
S8-32X1-2701-BLKOX-NY
• Saves money by eliminating the need for costly lock
washers, cotter pins or castellated nuts. You get a
close fit without expensive close tolerances. APM
pellets are less expensive than applying bottled
thread locking compounds at the point of assembly.
• APM pellets are virtually impervious to a wide range
of chemicals, water and motor fluids. They won’t dry,
shrink or lose resiliency when exposed to commercial solvents, alcohol, gasoline, oil, caustic soda, and
many other chemicals.

LOCKING STRIP (BAR) FOR SEELSKREW®
& SEELBOLT® SELF-SEALING FASTENERS
REUSABLE TO +550°F (288°C) PER
IFI 124, IFI 524 & MIL-DTL-18240,
VARIOUS NAS, AN, & MS CALLOUTS
A resilient engineered polymer bar (strip) is inserted into a precise
slot that has been milled into the threads making the fastener selflocking as well as self-sealing, while remaining fully adjustable. The
APM Strip delivers outstanding performance in both high and low
temperature extremes.
When assembled with a mating part the resilient APM Strip
(usually Nylon) is compressed which provides a locking action in the
thread instead of at the bearing surface due to vibration dampening
characteristics. The fastener is held in place without the use of
adhesives or thread distortion. The result is a self-sealing reusable
fastener that is both locking and repeatedly adjustable. APM Strips
are typically positioned one to three threads back from the end of the
fastener to assure ease of starting. Special strip positioning can be
tailored to fit your needs – contact Technical Sales for assistance.
FEATURES
HOW TO ORDER
• Under most conditions, our self-sealing fasteners
with Strips are unaffected by vibration or reversal
of stress. APM Strips lock whether the fastener is
seated or unseated.
• APM Strip fasteners require no costly lock-washers,
cotter pins, or castellated nuts. APM Strips provide
close fits without the expense involved in attaining
close tolerances, and are less expensive than
applying bottled thread locking compounds at the
point of assembly.
Specify the head type, thread size, length, followed by

HIGH-TEMPERATURE PATCH FOR LOCKING
& SEALING – PRE- APPLIED TO SEELSKREW®,
SEELBOLT® & SEALNUT® SELF-SEALING FASTENERS
HIGH-TEMPERATURE PERFORMANCE –
Maintains torque values through
temperatures from -70°F (-57°C)
to +500°F (+260°C)
A specially formulated Nylon high-temperature Patch is generally
applied to a minimum of 2-3 threads from the fastener end with 4-6
threads of coverage to assure ease of starting the nut/bolt assembly.
When the mating threads are engaged, the patch is compressed
creating a dam-like action on the opposite side of the coating
resulting in very strong metal-to-metal contact. When the hightemperature patch is fully seated, it forms a positive lock that will not
loosen, even under extreme vibration. This dam-like action adds to
the high-pressure sealing characteristics of the O-ring & groove
sealing design of our self-sealing fasteners.

• Saves Money & Time: APM Hi-Temperature Patch
eliminates the need for expensive lock washers,
cotter pins, or castellated nuts, and bottled thread
locking compounds at the point of assembly. The
Patch remains secure; fasteners coated with APM
patch can be automatically fed through standard
bowl feeders without fear of material falling off.
• Chemical resistance: APM HI-Temperature Patch
will not dry, shrink or otherwise be affected when
exposed to commercial solvents, alcohol, gasoline,
oil, caustic soda, jet fuel, etc.
*QPL-18240 & MIL-DTL-18240F requires gray nylon.
• Reusable: APM fasteners coated with the HiTemperature Patch can be reused repeatedly with
out damage to the threads. The patch is particularly
resistant to deformation which makes it ideal for
repeated use.
